Snyder's polyethylene riser for septic and cistern tanks, size 12
Part number 5160000W94201 is a Snyder Industries septic and cistern riser, moulded in polyethylene. A riser is the section that brings a buried tank's access opening up to finished grade, so the lid can be opened for pumping, inspection or a float change without digging. The 12 in the name is Snyder's size designation for this riser. It weighs 12 lb and ships by UPS in a 24 by 24 by 14 inch carton at 14 lb; Snyder lists the part at 29 inches. Snyder's drawing, linked on this page under Technical Drawing, is the source for the fit dimensions and the way it joins the tank and the next riser section.

What to check before you buy
- The tank. A riser has to match the opening on the tank it sits on. Tell us the tank part number and we confirm this riser fits it before the order ships.
- The depth to grade. Measure from the top of the tank opening to where the finished ground will be, after backfill and settlement, and order enough riser height to reach it. Risers are the part people order twice: the tank goes in, the hole gets backfilled, and only then is the gap measured. Order the tank, the risers and the lid together and the second trip does not happen.
- The lid. No lid is listed with this riser. Make sure the lid on your order matches the top of the riser stack and the traffic it will see.
- Burial and loads. No burial depth or traffic rating is listed for this part. Keep vehicles off the riser unless the tank maker's documentation says otherwise, and ask us if the riser will sit in a drive.
Installing it
Dry-fit the riser on the tank opening before anything is sealed, and check that the stack stands plumb; a riser that leans will not take its lid squarely. Seal every joint the way Snyder's drawing shows, because a riser joint is where groundwater gets into a septic tank and where odour gets out. Backfill evenly around the riser in lifts rather than dumping on one side, so the stack is not pushed off plumb. Set the lid and check that it can be opened before the machine leaves the site.
Shipping
The riser ships by UPS, 24 by 24 by 14 inches and 14 lb, from Snyder's Marked Tree, Arkansas plant. The listed price is before freight; the freight cost estimator gives the cost to your ZIP. If the tank ships by truck, order the risers with it and tell us; we arrange them to arrive together so the stack is on site the day the hole is open. Check the part number 5160000W94201 on the carton when it arrives.
